Hi,

Does D support any form of reflection or RTTI? I didn't see any mention of
this on the webpage.

thanks -mike

There's some support for it already. For any object you can allways get a
ClassInfo structure and see the name of the class, wich class is it's parent
and wich interfaces it implements:

import stream;

File f = File();
ClassInfo fci = ifile.classinfo;

printf("Class name: %s\n", fci.name);
printf("Base class name: %s\n", fci.base.name);

There's a pointer to the vtable, contructors, destructor and invariant
methods.

What I'm missing the most is the capability to see a class' methods and read
wich parameter types they need... but this seems quite difficult in a native
code compiled language.

You can see the ClassInfo source in /dmd/src/phobos/object.d

contructors is not available!!
